JOEL BRYANT, OF BROOKLYN, NEV YORK.

JOURNAL-BOX.

Specification of Letters Patent N0. 26,747, da1:ed January 10, 1860.

T0 all whom Lt may concern:

Be it known that I, J OEL BRYANT, of Brooklyn, in the county of Kings and State of New York, have invented a new and Im proved Mode of Constructing J ournal- Boxes; and I hereby declare that the following is a full and correct description thereof, sufiicient 110 enable others skilled in the art to make and use my invention, reference being made t0 the accompanying drawings, and t0 the figures and letters marked thereon, forming a part 0f this specification.

Figure 1 is a perspective view 0f my improved journal box. The letter A refers to the side pieces (A) and the 1etters R to the friction rol1ers (R), letter X t0 the axle 0f journal provided with said box, and the dotted lines to the central base B, not shovvnjn this figure (Fig. l), except by the dotted lines, Which indicate the position of the said base B in my improved journal boxes.

Fig. 2 represents the side pieces A and the said central base B 0f my improved axle or journal boxes, as shown in perspective by Fig. 1.

Fig. 3 represents a side view of one of my improved journal boxes (Fig. l) with the freut side piece (A) removed. This figure (F ig. 3) clearly shovvs the said central base B and the way in which the friction rollers R rast and roll thereon without coming in contact with the axles 01 journals (X) provided with the said boxes, as shown in Fig. l.

Fig. 4 represents the said central base B as disconnected from the side pieces A and indicates how it may be connected with the said side pieces A, to wit, by screw threads formed 011 projections (with a shoulder) 0n the ends ofthe base.

Fig. 5 represents a section of an axle or journal 'Ihe said Fig. 5 when viewed in connection with Fig. 2 indicates the way in Which the said journal boxes (Fig. l) are sei; upon ax1es or journals (X), to wit, by being permanently secured in the opening Z (formed to receive the axle X) in the center of the (otherwise solid) centra1 base B.

F ig. 6 has nothing to d0 with my invention further than simp1y t0 indicate (what erhaps is suificiently obvious) how the said oxes (Fig. l) may be set 111 thei1 cases, which ma be made of any desirable shape or size a apted 130 purposes for which the said journal boxes (Fig. l) may be requi ed.

My improved axle 01 journal boxes *ig. l) may be made of any desirable size or number of rollers R, so set within the said boxes as to rest and roll 011 the said central base B without coming in contact with the axles 01 journals (X) on which the said journal boxes (Fig. l) are set, and the said rollers R may be set and secured in the said journal boxes (Fig. l) like as in other jour nal boxes, providing the said rollers R rest and roll freely on the said central base B, which constitutes the chief merit and distinguishing characteristic of my improved journal boxes (Fig. l) and by which (centra1 base B) they may be known and distinguished from other friction roller ournal boxes.

The advantages 0f my invention are that my improved journal boxes (Fig. l) may be readily and strongly secured to the axles or journals provided therewith through the medium of the streng central base B, und as the said central base (B) prevents the the said friction rollers R from coming in contact with the axle or journals provided therewith there consequently will be no wear upon the said journals in the use of my improved boxes, and, as is obvious, the said base B, being considerably larger in circumference than the axle o1 joxirnal for which the said boxes are required, the said friction rollers R Will roll much easier on the said base B than 0n an ax1e, where the rollers leave spaces between them, into which the ax1e 0r journals press, so as t0 make an unsteady action fo1 the ax1e, as also to engender friction.

My improved boxes (Fig. l) Will enable the axle 01 journal to 1un more steadily and with less friction, the rollers having a larger base.

I am aware that there is nothing new in the use of friction roller journal boxes; but I am not aware that they have (prior to my invention) ever been made with a sentra1 base B, as herein described. Consequently, disclaiming all other modes of sonstrueting friction roller journal boxes as central base (B), substantially as herein dehitherto known and used, I desire to secure scribed.
